| 摘 要： | 本文提出了两种由体系温度(T)及汽液相组成(y,x)推算二元系总压(P)的直接法。并用T,x,y,P均已知的氯仿-乙醇、异戊二烯-乙腈二个二元体系数据,对所得公式进行验算,结果计算值与实验值吻合。此法可直接确定用流动平衡釜测汽液平衡时的总压;对同时测定了T,x,y,P的体系可进行逐点的P检验。

DETERMINATION OF SYSTEM PRESSURE AT VAPOR-LIQUID EQUILIBRIUM BY DIRECT METHOD |
| |
| Abstract: | Two methods for evaluating system pressure at vapor-liquid equilibrium in terms of temperature and vapor and liquid compositions are presented. The results calculated by above methods for two binary systems chloroformalcohol and acetonitrile—isopentylidiene, which T, x, y and P are given, are in good agreement with experimental results. These methods can also be used for pressure thermodynamic consistency test for systems where the T, x, y and P are all determined. |
